V2, Chap 15 (Sahha), I, p 464 - "Dali's Last Supper"

[Richard Ryan]

"...afterward they headed for the National Gallery, Pig having decided
the ought to have company.  Sure enough, in front of Dali's Last
Supper they found two government girls."

Properly called "The Sacrament of the Last Supper", Dali's painting
was - so a rather garbled Wikipedia tells us "[c]ompleted in 1955
after nine months of work[...]"   It "has remained one of his most
popular compositions ...upon its arrival in 1955 it replaced Renoir’s
A Girl with a Watering Can as the most popular piece in the museum."

Its presence here (i.e., in 1956, the year after its arrival the
National Gallery) is a testament to the author's finesse with telling
environmental and historical details.  I recognize that my reaction is
colored by my dislike for this particular canvas, but I register this
cameo appearance of a mediocre-to-awful painting (by an artist whose
work in the 30s is reasonably regarded as the product of genius)-  as
well as the boys discovery of Flip and Flop in front of it - as one
more piece of grotesque silliness in a chapter filled with the
Deliberately Ridiculous.
